PUMPING MECHANISNI.

SPECIFICATION forming part of Letters Patent No. 666,803, dated January 29, 1901. Application filed .Tune 16, 1899. Renewed October 6, 1900. Serial No. 32,286. (No model.)

To a/ZZ whom 112'; may concern:

Be it known that I, J AMES GANNON, a citizen of the United States, residing at Bristol, in the county of Washington and State of Virginia, have invented new and useful Pumping Mechanism, of which the following is a speciflcation.

This invention relates to pumping mechanism, and more particularly to that class in which a vessel is submerged at the bottom of a well and is adapted to receive water, which is then forced therefrom and out of the well by air-pressure, the vessel comprising two separate chambers which are adapted to be alternately lilled and exhausted.

The object of the invention is to provide a simple and efficient mechanism through the medium of which a continuous liow of water may be secured and in which, moreover, the air is exhausted through the same opening through which it enters, thus enabling the water-inlet valve to operate with the greatest efciency.

In the drawings forming a portion of this specification, and in which like numerals of reference designate corresponding parts in the several views, Figure l is a central longitudinal section of the submerged vessel and the supply-pipe with its valves, also of the delivery-pipe, other parts being in elevation. Fig. 2 is a transverse section taken through the submerged vessel at the left of the valve mechanism and showing all parts, with the section of the outlet-valves, in elevation. Fig. 3 is a detail section of a portion ofthe end of the vessel with its inlet-valve. Fig. 4 is a detail elevation of the air-inlet pipe with the regulating-valve thereon.

Referring now to the drawings, 5 represents a vessel comprising two equal chambers 6 and 7, separated by a partition 8 transversely of the vessel, which latter is preferably of a cylindrical form. This vessel 5 is adapted to rock in a plane including its axis, the rocking arrangement of said vessel being secured through the medium of pipe connections, including nipples 10 and 1l, rockingly mounted in stufhng-boxes in the ends of the stems of T- pipe connections 12 and 13, with which are connected pipes 14 and 15, the formerof which affords a means of supplying air to the chambers 6 and 7 successively, while pipe 15 receives and conveys water from the vessels upwardly and out of the well. Connected also with the T connections 12 and 13 are pipesections 16 and 17, which extend downwardly and are seated in sockets 18 and 19, formed upon a connecting-beam 20 and acting as a support therefor. The pipes 14 and 15 above the vessel 5 comprise T connections 2l and 22, the stems of which are connected by a brace-pipe 23,adapted to stiffen the structure, and which is stopped intermediate its ends, so that there may be no connection between pipes 14 and 15 therethrough.

The nipple 11` is formed upon the barrel 25 of a valve, having an inlet-opening 26 intermediate' its ends, and through which opening the nipple 1l communicates with the barrel 25. Equidistant from and on opposite sides of the opening 26 and in the opposite wall therefrom are formed two outlets or openings 27 and 28, of which the opening 27 communicates with the bore of a tubular extension 29, which is continued through the wall of the chamber 6 and has connected therewith an inwardlyand upwardly extending pipe 30, which terminates in the upper portion of the chamber adjacent the partition 8. Intermediate the opening 27 and the adjacent end of the barrel 25 is an opening 31 (shown in dotted lines in Fig. 1 of ythe drawings) and whichV communicates with a tubular outlet 32.

A tubular extension 35, communicating with the opening 28 in the barrel of the pump, projects into the chamber 7 of the vessel and has connected therewith a pipe 36, which extends inwardly and upwardly and parallel with the pipe 30 and terminates adjacent the upper wall of the vessel and the partition 8.

An outlet-opening 37 is formed in the upper wall of the barrel 25 intermediate the opening 28 and the adjacent end of the barrel, as shown in dotted lines in Fig. l, which opening communicates with a tubular extension 38, as shown in Fig. 4.

A removable plug is fitted in one end of the barrel 25, while in the other end is arranged a stuing-box 39, through which is passed a Valve-rod 40, having arranged thereon, within the barrel, two pistons 4l and 42, so positioned that when piston 42 is between IOO the opening 27 and the adjacent end of the barrel the piston 41 will lie intermediate the openings 28 and 26, so that any air that may be forced through pipe 14 may pass through the nipple 11 and into the valve-barrel and thence through the opening 27 into the extension 29 and pipe 30 into the chamber 6. At the same time the chamber 7 will have a direct communication with the exterior of the vessel through the pipe 36, the extension 35, the opening 28, the barrel, the opening 37, and extension. 38. When the valve-rod is moved to its opposite position, the How of air from pipe 14 inwardly will be through pipe 36 to the chamber 7, While chamber 6 will communicate with the exterior of the vessel through the valve-barrel and the extension 32. In order to eect this shifting of the valve-rod and the pistons carried thereby, I secure to the barrel 25 ears 45, between which is pivoted an L-shaped lever 46, one end of which is slidably connected with the valverod, while the other end thereof is extended through a keeper 47, carried by the pipe 17. Thus it will be seen that as the vessel 5 is rocked the connection of the lever 46 with pipe 17 will cause an alternate shifting of the valve mechanism from one position to the other. In order to cause this rocking of the vessel 5 and at the same time to cause the chambers 6 and 7 to alternately ill with water, I form an opening in the outer end of each chamber 6 and 7 and adjacent the upper wall thereof, each of which openings has an inwardly-opening valve 48, as shown in Fig. 3 of the drawings, so positioned that when the vessel is tilted the uppermost valve will hang open, While the lowermost valve will be closed by gravity. Guard-netting 49 is se cured over the outer ends of the openings just described to prevent ingress of gravel and other objectionable matter.

In order to allow the flow of water from the chambers 6 and 7 at the time air is being forced thereinto, I arrange at each side of the partition 8 an outlet-pipe 50 and 51, which pipes are extended upwardly and outwardly and are connected with the extensions 52 and 53, which enter the wall of the vessel 5 at 'each side of the partition 8 and which are formed upon the casings of outwardly-opening check-valves 54 and 55 in the legs of a U-shaped connection upon which the nipple 10 is formed. Thus it will be seen that if the apparatus be placed in a well with the vessel 5 submerged and one of the chambers be allowed to fill with water it will immediately sink, shifting the pistons 41 and 42 to a position which will open the sunken chamber to the air-inlet pipes, and thus if airpressure be contributed to the pipe 14 the Water will be forced out of the sunken chamber and through its respective pipes 50 or 51 and pipe l5 and thence upwardly and out of the well. At this time the valve 48 in the uppermost chamber is open and water is running into it. This filling of the uppermost chamber will continue until such an amount of water has been exhausted from the sunken chamber as to allow it to be overbalanced by the other chamber, when the vessel will rock to t-he other position and will shift the valve to its opposite position to allowthe forcing of the water out of the last sunken chamber and to allow the passage of air out of the chamber just cleared of the water to permit the passage of Water thereinto. This operation will be continued so long as the supply of air be contributed through the pipe 14, the checkvalves 54 and 55 preventing back pressure of water from the chamber being cleared into the opposite chamber.

It will be seen from this description that by this intermittent and constant rocking of the vessel a continuous iow of water may be secured, while the parts are in themselves so simple in construction and operation as to insure an efficient operation at all times.

It will be understood that the shape of the vessel may be varied as desired, that the frame may be altered, that the general construction and arrangement may be varied without departing from the spirit of the invention,and that any desired means connected with the beam 20, such as a beam 60, having upwardly-projecting stops at its ends, may be employed for limiting the rocking motion of the vessel.

Having thus described the invention, what is claimed isy 1. The combination with a supportingframe comprising inlet and outlet pipes having openings therein, of a vessel comprising separate chambers, hollow trunnions for said vessel by which it is rockingly'mounted in communication with the openings of said pipes, a connection at each side of the separating-partition of said chambers leading to one of said trunnions and having a common outwardly-opening valve, a valve-barrel carried by the opposite trunnion and having openings communicating with the chambers, said barrel communicating also with its trunnion, air-outlet openings in said barrel, and means for alternately opening and closing said first-named openings with respect to the inlet-pipe and for alternateljT opening and closing the air-outlet openings in the barrel with respect to the openings that communicate with the chamber.
